Abstract
The concentration of a water soluble corrosion inhibitor formulation in the water of an aqueous system is monitored by a UV absorption method which is based upon the measurement of the absorbance of a component of corrosion inhibitor formulation. The method is particularly suited to on-site determinations of inhibitor residuals in large aqueous systems, such as in oil field applications, which have an acute need for rapid and adaptable assays, so as to provide precise information before corrosion damage can occur.
